GASOLINE CAMP STOVE.

Application inea March s, 1927." sez-iai no. 172,302.

Automobile tourists, hunters, fishermen and others who do a considerableamount ot outdoor camping, iind it moreconvenient to employ for theircooking Va stove that burns hydrocarbon luel, such as gasoline, than todepend' on the wood camp tires. The great prevalence of automobiletourists has resulted in wood families along the highways, which makesit imperative that some other means ot producing heat than the old andwell known wood lire must be provided.

It is the object of this invention to produce a camp stove of the typereferred to which shall be oi' simple and substantial construction andin which the burner assembly and the 'uel tank shall be rigidly securedto the casing in suoli manner that they will be fully protected againstinjury during transporta tion and will be prevented from beingaccidentally. displaced with respect to each other.

lt is the further object ofthisinvention to produce a stove of this typein which the fuel tank shall be separated 'from the burner assembly bymeans o" a double partition wall whose interior is in tree communicationwith the air and whose upper portion is provided lwith a plurality oitopening-s so that when the burners are in operation, a` continuousstream ot air will circulate between the walls of the partition andthereby produce a heat insulating effect that prevents the tank 'frombecoming unduly heated. i rllhe above and other objects which may becomeapparent as the description proceeds are obtained by means of aconstruction which briefly described, is as follows:

A rectangular metal casing having a bottom and a hinged top is providedfor the pur- Y pose of enclosing` the burner assembly Vand the fueltank. rThis casing is divided into two compartments by means of ahollov7 longitudinally extending partition. rllhis partition `is securedto t-he'bottom and the latter is provided with alarge number ot holesthat communicate with the partition. A large number of holes is alsoprovided near the top of the 0 partition so that air may iow upwardlybetween the walls of this partition whenever it becomes heated. Theburner assembly is lo* cated in-one of thecompartments and the fuel tankis located in the other. The longitudi- ,5 nally extending partitionserves as a heat insulating medium and protects the tank .from the heatgenerated by the burner while in operation. l

Having thus briefly described` the invention the same will now bedescribed in detail, and reference for thispurpose will be. had to theaccompanying' drawing in which the preferred embodiment hasbeen'illustrated, and.

in which Fig. 1 is a plan view ol the stove with parts broken awaytobetter show theV construction; Fig. 2 is an elevation looking in thedirec'-l tion of the arrow 2 in Figure 1; o Fig. 3 is a transversesection taken on line 3f-.3, Fig. 1 and shows the cover in closedposltion;

Fig. 4 is a section taken Online 4-4, Fig.y 1, and fshows the preferredconstruction of the hollow partition; and

Fig. 5 is a section taken on 5-5, Fig. 1, showing the manner otconnecting the generator tube to the burner.` 1 l Numeral 1 designatesthe. bottom of the casing. This casing has been shown as of rectangularshape and is provided with ends 2 and 3. These end members are connectedat their respective` ends by sides 4 land 5. Side 4 is of the sameheight as the endmembers 'but side 5 is much lower.; The end members 2and 3 have portions 6 and 7 which are bent at right angles andwhoselower edges are secured to the side 5 in the manner shown in Figure 2. Acover 8 is hingedly connected to the upper edge of sidel 4 and isprovided with a. downwardly extending portion 9 which closes thelopening formed between the top of the `side 5 and the inclined edges ofparts 6 and' 7. The casing is divided into two compartments A and B ybymeans of a `hollow partitionA which comprises two pan `allelmembers 10and V11 of sheet metal which are integrallyconnected along their'upperedges and are provided along their lower edges with outwardly extendingfeet 12. This partition is secured to the bottom 1 by means of tongues13 that are Jrormed integrally from the bottoni 1 and are bent over thefeet 12 in the manner shown in Figure 4. A rabbet 14 is providedV alongthe upper edge of this partition wall sofas to form a support for thefree edge or' the grate 15. The bottom memberl is provided with a largenumber of openings 16, which communicate with theinterior of the hollowpartition, andthe partition member 10 is provided with a lplurality ofopenings 17 along its upper edge, so

that air may freely circulate in an upward direction through theinterior of this Vhollow Y Loca-ted within the compartment 3A isV a'partition, The bottom of `cfoiiipartiiient Bis also provided with tworows ot openings 1,8,

which permit the tree circulation of air.

-k Having thus described the-inventioiiwhat s claimed as new isc 1. Acampl stove.` comprising, .maconibiiiaf tion, acasing having avbottoinhinged cover, ahollow partition dividingfthemterior top forming' a ofthe casing into twoy compartments, a

burner assembly located within one of said compartments, a fuel tanklocated adjacent the partition within the other compartment, means forconducting fuel from the tank to the burner assembly and means forproducing an upwardly flowing air current through the interior of andadjacent to said partition when the stove is in operation whereby thetank will be protected from the heat.

2. A camp stove comprising, in combination, a casing having a bottom anda hinged cover, a partition for dividing the casing into twocompartments, said partition being formed from two parallel spacedmembers provided with a plurality of openings along the top, Vthe bottombeing also provided with a plurality of openings communicating with theinterior of said partition, whereby air may flow through the partitionwhen the latter is heated, a burner assembly in one of saidcompartments, a fuel tank in the other compartment and means forconducting fuel from the tank to the burner assembly.

3. A camp stove comprising, in combination, a casing having side walls,end walls and a cover, a partition extending across the interior of thecasing so as to divide it into two compartments of unequal size, aburner located in the larger compartment, a fueltank located in thesmaller compartment, and a conduit extending from the fuel tank to theburner, the sides of the partition being in free communication with theair below the edges of the sides and ends of the casing whereby anunobstructed circulation of air may take place on both sides of thepartition.

4. A camp stove comprising, in combination, a rectangular casing havingspaced parallel side walls, spaced parallel end walls and a cover, apartition extending across the interior of the casing and dividing theinterior thereof into two compartments of un equal size, said partitionbeing formed from two spaced wall members, the space between the wallmembers being in communication with the atmosphere at the bottom and atthe top of the partition whereby air may flow through the interior ofthe partition when the latter is heated, a burner in the larger compartment, a fuel tank in the smaller comparu ment adjacent the hollowpartition and means for conducting fuel from the tank to the burner.

In testimony whereof we affix our signatures.
